12 Claims.

The invention herein disclosed relates to binders of the type in which rings binding the leaves together enter in correspondingly placed notches in an arched support and are held in that relation by a pin or key extending through the arch and through the rings disposed in the notches of the arch.

- The purpose of the present invention is to improve such constructions, particularly in the matters of facilitating the entry of the securing pin, enabling the use of a lighter and less expensive pin and effecting reliable and at the same time releasable holding and positioning of the pin in the arched supporting structure.

Other objects and the novel features of construction, combinations and relations of parts by which all objects of the invention are attained are set forth and will appear in the course of the following specification.

The drawing accompanying and forming part of the specification illustrates a present preferred embodiment of the invention. Structure however may be varied from this disclosure, all within n lower portion of the support shown in Fig. l.

the true intent of the invention as will be apparent from the following specification and claims. Fig. l is a broken plan View of a multiple section binder incorporating features of the invention. Figs. 2 and 3, yare enlarged broken sectional details on substantially the planes of lines 2-2 and 3 3 of Fig. 1.

Fig. 4 is a broken enlarged plan view of the Fig.Y 5 is an enlarged and broken longitudinal rsectional view as on line 5 5 of Fig. l.

Fig. 6 is a detail View of one of the securing pins.

In the illustration, the supporting structure comprises a book back l, having integrally attached covers 8, 9, and having secured to it as by rivets IIB, a back plate II. 'On this back plate there is secured a plate I2, having upstruck arches 4vI3, notched at I 4, to receive the binder rings I5.

` The binder rings are shown as oi the Wire-O design consisting of double strand rings formed from a continuous length of Wire bent in zig-zag fashion to provide these double strand rings connected in spaced parallel relation.

kThe structure shown is a three section binder and consequently the plate I2 is formed up with three parallel archways I3, each notched to re- 'ceive the rings of one binder section. There may be more or fewer sections however, for while the inventionk is of particular advantage for multiple section large thick books, special features of the invention may be found equally desirable for smaller single section binders.

The pins for retaining the binder rings between the loops formed by the notched arches differ from those usually employed in that they consist each of a relatively light and exible round wire I6, as distinguished from a heavy, stiff and practically rigid rod or hat bar such as heretofore employed. This lighter and more exible wire will yield and bend with the bending of the binder rings and support in the normal handling of the book and to compensate for variations in dimension of parts incidental to manufacture. This smaller diameter wire permits of the loops or, arches being made smaller and lighter material to be used for the supporting plate I2.

To give the key wires a denite frictional grip with the arches and the binder rings they may be bent as indicated at i l, Figs. 5 and 6, to offset one portion with respect to an adjoining portion, so that in being entered in the archways they will be to some extent straightened and be put under tension to a degree dependent on the extent of such straightening.

To facilitate the entry of the flexible and more or less flimsy wire into the end of the notched archway, a special guide is provided consisting in the present disclosure of a lug I8, partially detached and struck up from the body of plate I2, and having in its upper surface a tapered channel I9, leading directly into the upper portion of the end loop of the archway. This enables the wire to be easily entered by simply resting the end of the wire in the channel I9, and which as thrust is applied, will center and direct the wire straight on into the end of the archway. This guide also by holding the wire up in the top of the arch tends to bind it against the top and thus frictionally retain it in place. If the wire is bent, as indicated, this guide also will exert a straightening tendency and hence further operate as a retainer for the wire.

Some convenient form of handle is preferably provided.- on the wire. For example, the end of the wire may simply be bent at approximately a right angle to provide an integral form of handle such as indicated at the right at 25, in Fig. 1. In another embodiment, a small flat finger plate 2|, is swedged onrthe end of the wire at 22. In this form' of construction, the bottom edge 23, of the nger piece slides over the surface of the back plate II, Fig. 5, to hold the wire up in the top of the arch and to frictionally retain the wire nonrotatably in position in the supporting arch. In Fig. 5, the binder rings are omitted for better illustration of the deformed retaining pin or wire. The binder loops when in position however would have the effect of tending to straighten the wire so that in actual use, the wire would not remain bent to the extent indicated and would in fact be restored practically to straight condition, held so by the cooperative action of the retainer loops and the binder loops in their relatively overlapping relation.

The pin guiding steps I8, at the entrances to the retainer arches need project only a slight distance. Preferably however they will project somewhat below or beyond the end of the bound sheets, after the manner indicated in Fig. 4, so that the ends oi the retainer arches will be found by the binder wires even though practically hidden by the bound sheets Ita.

The plate I2 carrying the retainer arches and entrance guides may be fastened in position in various ways, as for instance, by means of retainer lugs 24, struck up from the back plate Il,

through openings 25, and bent over the face of ,n

' tainer arch. As indicated in Fig. 5, the pin guides I8 at the entrances to the retainer loops may, by reason` of engagement of the finger lugs therewith, limit the extent to which the pins can be inserted in the holder loops. The finger pieces 2| of the retainer wires when fully in position are held by the back plate il, against turning and in definite upright position as shown at the left in Fig. l and Fig. 5, where they are readily seen and can be conveniently grasped.
